General Surgery Flashcards
What is the best way to distinguish gastroesophageal reflux from other sources of epigastric distress?
PH monitoring his best to establish the presence of reflux
When should endoscopy and biopsies of the esophagus be done?
If there is concern the damage may have been done to the lower esophagus or peptic esophagitis and possible development of Barrett’s esophagus
When is esophageal surgery indicated?
Long-standing symptomatic disease that cannot be controlled by medical means, or anyone who developed complications, ulceration, stenosis and it’s imperative if there are severe dysplastic changes.
What type of surgeries done on the esophagus?
Resection or laparoscopic Nissen fundoplication
How can motility problems be diagnosed?
Barium swallow is typically done first. Manometry studies are used for definitive diagnosis.
How is achalasia diagnosed?
manometry is diagnostic. X-rays show megaesophagus.
Treatment for achalasia?
Balloon dilatation done by endoscopy
Dysphagia that is worse for liquids
Achalasia
Dysphasia starting with meats then other solids then soft foods eventually liquids and finally in several months saliva + significant weight loss that is almost always see
Cancer of the esophagus shows this classic progression
Next step in management if esophageal cancer is suspected?
Barium swallow must precede the endoscopy to help prevent inadvertent perforation. Diagnosis is established with an endoscopy and biopsies. CT assesses operability, but most cases can only get palliative rather than curative surgery.
What are the two types of esophageal cancer?
Squamous cell carcinoma – man with a history of smoking and drinking, blacks have high incidence. Adenocarcinoma - long-standing gastroesophageal reflux.
Mallory-Weiss tear
Belong forceful vomiting eventually bright red blood comes up
Do you diagnose a Mallory-Weiss tear?
Endoscopy establishes diagnosis, and allows for photocoagulation, laser.
Boerhaave syndrome
Starts with prolonged, forceful vomiting leading to esophageal perforation. There is continuous, severe, wrenching epigastric and low sternal pain of sudden onset, soon followed by fever, leukocytosis, and a very sick – looking patient.
Next step in management if Boerhaave syndrome is suspected?
Gastrografin first, barium if negative is diagnostic, and emergency surgical repair should follow. Delay in diagnosis and treatment as grave consequences.
What is the most common reason for esophageal perforation?
Instrumental perforation of the esophagus. Shortly after completion of endoscopy symptoms similar to Boerhaave syndrome will develop. There maybe emphysema in the lower neck. Contrast studies and proper pair are imperative.
Which patient population is more likely to get gastric adenocarcinoma? What are the typical symptoms?
More common in the elderly. There is anorexia, weight loss, and vague epigastric distress or early satiety. Occasionally hematemesis.
How do you diagnose gastric adenocarcinoma and what is the treatment?
Endoscopy and biopsies or diagnostic. CT scan helps assess operability. Surgery is the best therapy.
Incidence of gastric lymphoma versus gastric adenocarcinoma?
Gastric lymphoma is nowadays almost as common as gastric adenocarcinoma. Presentation and diagnosis are similar.
Treatment for gastric lymphoma?
Chemotherapy or radiotherapy. Surgery is done if perforation is feared as the tumor melts away. Low-grade lymphomatoid transformation (MALTOMA) can be reversed by eradication of H. pylori.
What are the signs and symptoms of a mechanical intestinal instruction?
1)Colicky abdominal pain and 2)protracted vomiting, 3)progressive abdominal distention if it is a low obstruction, and 4)no passage of gas or feces. Early on, 5)high pitch ball sounds coincide with the colicky pain after a few days there is silence.
How do you diagnose and mechanical intestinal obstruction?
X-rays will show distended loops of small bowel, with air – fluid levels.
What causes mechanical intestinal instruction?
Adhesions in those who have had a prior laparotomy.
Treatment of mechanical intestinal obstruction
NPO, NG suction, IV fluids, hoping for spontaneous resolution or watching for early signs strangulation. Surgery if conservative management is unsuccessful, within 24 hours in cases of complete obstruction or within a few days in cases of partial obstruction.
